Aviation safety reports, made easier to study

NTSB Reports is an independent research and search tool for public aviation accident and incident records. It brings NTSB aviation reports, structured fields, docket files, extracted figures, photos, videos, and update history into one searchable interface.

The goal is practical safety education: make it faster to find relevant investigations, compare similar events, review factual records, and understand the evidence behind probable-cause and preliminary reports.

The investigative work and source records belong to the National Transportation Safety Board and the published investigation record. This site is not affiliated with or endorsed by the NTSB.

The accident occurred during a takeoff on an ice-covered runway. The pilot reported that when the airplane encountered a large patch of ice on the runway it began to drift left of the runway centerline. He immediately reduced engine power and applied brake pressure, but the airplane continued to slide toward the runway edge. The airplane impacted a snow bank and nosed over. A post accident examination revealed that the engine firewall, both wings, and the empennage components were substantially damaged. The pilot reported that there were no preimpact mechanical malfunctions or failures that would have precluded normal operation of the airplane.
